I wasn't suggesting a switch to Bionic. Bionic, Droid 3, and Droid 4 are missing the FM Radio App. The one in the message I provided defiantly works for Bionic and Droid 3. I don't know about Droid 4. I think it is likely. Worth a try?
The message has the link to the apk file. I just downloaded it to a PC, transferred it to the SD-Ext card with a USB connection, found it with the Files app, double-clicked on the file, and selected Install.
(You will find that there is ONE person in the Verizon store that everyone goes to for their technical information. Find that person.)
